Abstract
INTRODUCTION: The proportion of elderly population has been constantly increasing over last few years. Polypharmacy is unavoidable in the elderly as they often suffer from multiple co-morbidities. Potential drug-drug interaction due to polypharmacy and potential inappropriate medication among the elderly must be carefully assessed. AIM: To find out polypharmacy and potential drug-drug interactions among elderly patients admitted and discharged in Department of Medicine. MATERIALS AND METHODS: This study was carried out on 100 patients above 65 years of age both males and females. Data was collected through review of case sheets. Polypharmacy was observed based on admission and discharge prescriptions. Frequently occurring drug-drug interactions were assessed using online checks. RESULTS: Mean number of drugs prescribed to patients on admission (7.61 ± 3.37) was more than that on discharge (5.48±2.46). More than half of these patients received 5 to 9 number of drugs. On admission 52.69% potential drug-drug interactions were observed and on discharge 52.91%. Most common drug interactions observed in both the groups were of moderate grade. CONCLUSION: From the present study we can conclude that polypharmacy leads to more potential drug-drug interactions. To improve drug safety in this high-risk population, appropriate prescribing is very important.
